In addition to competition prize based on final result in leagues, an entrance prize may be given to teams corresponding to club level they will play in coming season.
I am sorry that my proposal is actually not relating to your topic. But I suddenly have this idea and bring it to here because it also relates to in change club level structure.
My proposal is not thoroughly considered and very weird. Even if a low quality team is brilliant and win a league, it is still possibly assigned to lower levels than those teams ranking below it. Teams will be rewarded for good performance as well as high quality! Haha, this is so weird. But I don't like seeing some leagues in same levels has huge difference in qualities comparing with other leagues in same level. This can solve it. I don't mind playing weird level structure like this.
I know my proposal will never happen. In fact, I don't like significant changes. I support maintaining current structure but adopting pure random drawing.
